When feeding water to the CaviBlaster

® 

power unit with the feed pump, connect 

the 1″ diameter

  clear  PVC  feed  hose  to  the  cam-lock  plug  on  the  inline  strainer 

inlet.

 

 

The feed hose has the feed pump on one end and a cam-lock socket on the other end. Insert the 
electrical plug powering the feed pump into the waterproof electrical outlet on the end of the 
power unit cart under the handle. Ensure that the knob on the plug is facing up and mates with 
the notch in the outlet cover. 

If the plug is engaged upside down, the pump will turn in reverse. 

Ensure that the feed hose is connected to the pressure pump, the feed pump is  submerged in 
water,  and  the  wiring  splice  is  kept  dry  prior  to  starting  the  feed  pump. 

Either  fresh  water  or 

seawater can be used with this system. 

Note: The feed pump has had a neoprene check valve installed in the discharge. This valve will prevent water from 
draining out of the feed hose through the feed pump when the pump is turned off. However, this check valve 
somewhat restricts the flow of water from the pump. If maximum water flow is required from the feed pump, the 
check valve and stainless retaining washer can be removed from the pump discharge by removing the black hose 

barb fitting. 

NEVER TURN OFF FEED PUMP WHILE WORKING. 

 

 

 

 

 

 

 

 

 

When feeding the CaviBlaster

® 

with an alternate water source, 

the source must supply water at a 

volume of greater than 6 gallons per minute at a maximum pressure of 70-psi

. Connect the water 

source to the inlet of the pressure pump (Figure 10). 

Ensure that the feed hose is connected to the 

pressure pump and the water is on prior to starting the pressure pump.
